LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 595,826, dated December21, 1897.

l Application filed May 3,1897. Serial No. 634,939. (No model.)

bya handle when required for filling or otherwise.

In the annexed drawings, Figure l is a side view of the apparatus withthe casing in section. Figs. 2 and 3 show in dierent positions /thearrangement for disengaging the screw from the clockwork, so that thepiston may be moved by hand. Fig. 4 is a plan of the crank-handle bywhich the apparatus is moved by hand. The head by which the handleengages is shown in section. Fig. 5 illustrates the arrangement of theclockworktrain. Fig. 6 shows in plan a device for stopping and releasingthe clockwork. Fig. 7

shows, on an enlarged scale,the balance-wheel and the pivots by which itis carried.

a is a cylindrical barrel for containing the lubricant. It is lled byremoving it from the cover b at its lower end. This cover is adapted bya screw-thread to the machine which requires lubrication, and it has aduct h through it, through which when the apparatus is at work thelubricant, such as vaseline, is gradually expelled.

c is a piston workin g in the cylinder a, which is driven downward bythe rotation of the screw d, and is so made as to expel the lubricant.On the head of the screw d a toothed wheel e is fixed, and this isengaged by a pinion f' on the axis f. On the same axis is another pinionf 2, which can be brought into engagement with the toothed wheel g ordrawn up out of engagement when required. It is shown in thefirst-mentioned position in Fig. 2 and in the latter position in Fig. 3.For this purpose the axis f is so arranged that it can slide in itsbearings in the casing. It is pressed downward by al spring f8, which iscompressed when the axis is drawn upward.

h is a head which is received by the axis f and is secured to it by asmall screw h'. To the head h a crank-handle t' is readily applied, afork on the handle embracing the neck of the head, as is seen in Fig.4..

t" is a latch by which the handle can be locked fast tothe head.

The toothed wheel gis upon a spring-barrel, such as is common inclockwork. The spring is wound up from time to time, as required, by akey applied to the square g'.

In Fig. 5 the clock-train can be traced. The wheel g drives the pinion1, and the wheel 2 on the same axis with the pinion 1 drives the pinion3, which is fast with the wheel 4, which drives the pinion 5, which isfast with the wheel 6, which drives the pinion 7, on the y axis of whichis the escapement-wheel.

la is the'balance-wheel, which controls the escapement in the ordinarymanner. The axis of the balance-wheel is coned at the ends, asis seen inFig. 7, and these cones enter small holes drilled into the studs lo k.The arrangement is such that the points at the ends of the spindle arenot exposed to wear, and the holes in the plugs also serve to retain theoil with which the pivots are lubricated.

Z is a light spring-finger which can be brought against the periphery ofthe balancewheel k to retain it at rest, as is shown in Fig. 6. The ngeris carried by an arm Z', which can turn about a center Z2. The handle Z3is upon it, and by turning it a short distance in the direction of thearrow shown in Fig. 6 the clockwork is liberated. lm, is a glazed windowin the casing, through which the clockwork can be inspected, or thecylindrical casing containing the clockwork may be wholly of glass.

When the apparatus requires illing, the part a is detached from the partb, the clockwork is stopped, and the handle i is applied. The handle isdrawn upward, thereby causing the pinion f2 to be disengaged from thewheel g, while nevertheless the pinion f' remains engaged with the wheelc. Then by turning the handle the piston 'c is run up to the top of thebarrel a. The barrel is then lled with the semifluid lubricant and isre- IOC) placed upon the lower part I). Then by again turning the handle1I in the opposite dii-eetion the lubricant is fed downward through theduet b. As soon as it commences to issue the handle is removed, theclockwork is started, and the clockwork will then slowly continue, thedownward movement of the piston feeding the lubricant downward at theslow rate to which the instrument is adjusted.

The combination of a grease-container, a piston by which the grease isexpelled therefrom, a screw which propels the piston, a toothed Wheel eoperatively connected with the screw, a clockwork that :normally drivesthe screw, an endwise-movable axis and two y GUSTAV WALCH.
